Adding Inventory Items to a Device Type without an associated Inventory Item Type throws: 'component' does not resolve to an item that supports prefetching - this is an invalid parameter to prefetch_related().

NetBox version

3.2.0-beta2

Python version

3.9

Steps to Reproduce

1. Create a Device Template

2. Add an Inventory Item without adding a Role

3. Click Create

Expected Behavior

The expected behavior would be for it to come back to the inventory items page, as per normal:

Observed Behavior

The server has an issue preloading related items. Probably because the inventory item has no role, thus nothing to preload.

Sorry if this one has been raised before. I couldn't find a reference, but I probably didn't look correctly.

You can fix it if you assign a role, but otherwise, it stays broken. I haven't checked after assigning an inventory item to an inventory without a role.
